OVAL WHEEL METER

Oval Gear Meters-Emulsion & Oil

The oval wheel meter was invented by Bopp & Reuther and
protected as a patent in 1932. The first Weights and Measure
approval was granted in 1933 by the PTR in Berlin.

Measurement Principle:
Oval wheel meters are direct volumetric meters for liquids.
Their measuring element consists of two toothed precisions
oval wheels, rolling on each other driven by the fluid pressure.
Such a defined amount of liquid is transported through the
meter for each rotation of the oval wheels.

Therefore, the number of revolutions is an accurate measure
for the amount of liquid flowing through the meter.

Applications

Volume measurement of liquids and liquefied gases in loading applications for chemical and petrochemical industry, petroleum
industry and of food and beverages:

  • in the oil industry for the measurement of crude oil or
    refined products or for the measurement of LPG
  • in dosing and loading applications for the measurement
    of defined amounts of various fuels and additives
  • in the petrochemical industry for measuring of products
    such as ethylene or propylene liquid
  • in the chemical industry for measuring of various acids
    or alkalis
  • in mechanical engineering for measurement of process
    liquids or lubricants
  • in shipbuilding for measuring of fuel consumption as
    well as lubricating oil

TYPE OD

Application

The focus is on the measurement of non-conductive liquids. This meter is designed for the measurement of e.g. oil or demineralized water. Due to the measuring principle, there is no need for an inlet or outlet section.

Characteristics

  • direct measurement of volume
  • measurement of non-conductive and conductive liquids
  • high accuracy / repeatability also for small quantities
  • high long-term stability
